DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 2 and 3, an exercising device in accordance with the preferred embodiment of the present invention comprises a main frame 10, a retractable bar 20, two operation handles 25, a support frame 30, and an arc-shaped rocking bar 60.

The main frame 10 has a first end formed with a plurality of adjusting holes 14 and a second end provided with a transverse support bar 11. The main frame 10 has a mediate portion provided with a fixed tube 13. The main frame 10 is provided with two fixing plates 12 for mounting a backrest 40 by a plurality of screw members 90.

The retractable bar 20 is retractably mounted on the first end of the main frame 10 and has a first end formed with a positioning hole 24 aligning with one of the adjusting holes 14 of the main frame 10 and a second end provided with a transverse fixing bar 21 for mounting a head cushion 50 by a plurality of screw members 900.

The exercising device further comprises a substantially V-shaped elastic plate 22 mounted in the retractable bar 20 and having a distal end provided with a positioning stub 220 extended through the positioning hole 24 of the retractable bar 20 and detachably locked in one of the adjusting holes 14 of the main frame 10.

Each of the two operation handles 25 is adjustably mounted on the support bar 11 of the main frame 10. Each of the two operation handles 25 has a first end provided with a protective grip 26 and a substantially arc-shaped second end. Each of the two operation handles 25 has a mediate portion provided with a transverse adjusting bar 27 adjustably mounted in the support bar 11 of the main frame 10.

The support frame 30 is substantially inverted Y-shaped and is pivotally mounted on the main frame 10. The support frame 30 has a first end formed with a substantially U-shaped pivot rack 32 pivotally mounted on the fixed tube 13 of the main frame 10 by a bolt 34 and a nut 36 and a second end formed with two support legs 38 each pivotally provided with a roller 31 by a bolt 902 and a nut 904. The pivot rack 32 of the support frame 30 is provided with a protruding limit rod 80.

The rocking bar 60 has two ends each fixed on the main frame 10 by a screw member 906. The rocking bar 60 is provided with a protruding limit rod 802.

The exercising device further comprises two opposite belts 70 each having a first end secured on an end of the limit rod 802 of the rocking bar 60 and a second end secured on an end of the limit rod 80 of the pivot rack 32 of the support frame 30.

As shown in FIGS. 2-4, the positioning stub 220 of the elastic plate 22 mounted in the retractable bar 20 is extended through the positioning hole 24 of the retractable bar 20 and detachably locked in one of the adjusting holes 14 of the main frame 10, so that the retractable bar 20 is retractably mounted on the first end of the main frame 10 to adjust the height of the head cushion 50 so as to fit users of different heights.

In operation, referring to FIGS. 2-8, the user's two hands hold the protective grips 26 of the two operation handles 25, with his/her back being rested on the backrest 40, and with his/her head being rested on the head cushion 50 as shown in FIG. 7. Then, the user's body is moved backward to press the main frame 10 backward as shown in FIG. 8 so as to rock the rocking bar 60 and to pivot the support frame 30, so that the support frame 30 is pivoted from the position as shown in FIG. 5 to the position as shown in FIG. 6 to extending the belts 70. Thus, the user has to exert a force to overcome the elastic force of the belts 70, thereby achieving the purpose of exercising the user's waist.

Accordingly, the user has to exert a force to overcome the elastic force of the belts 70, thereby achieving the purpose of exercising the user's body. In addition, the rocking bar 60 is arc-shaped to satisfy the ergonomic design, so that the user can operate the exercising device in a comfortable and safe manner. Further, the user can operate the exercising device easily and conveniently, thereby facilitating the user operating the exercising device.
